▸ Decision summary
Grammarly Premium and Typeahead both try to make you a faster, cleaner writer, but they attack the problem from opposite ends. Grammarly corrects what you already wrote, checking grammar, tone, and originality in the cloud. Typeahead predicts what you're about to write, running a local AI model on your Mac to finish your sentences before you type them.
Pick Grammarly Premium if you write across many devices and platforms and want tone and plagiarism checking built in. Pick Typeahead if you live on a Mac, want your text to stay off someone else's server, and would rather have your sentences finished for you than corrected after the fact.
